all you guys who say your bearings were dead on and in spec, at how many miles was this?

i have 95,000 on my motor and i'm rebuilding...i dont want to buy bearings only to find that they dont fit and drop more cash on OEM bearings

 

I used ACL on my rebuild...no problems at all...KS-MOTORSPORTS.com....over nighted..no problem..

 

I honestly don't understand why this is a question anymore. Machining tolerances are so exact nowadays that ANY companies bearings should be perfect.

having said that I used ACL for my build and they where perfect.

I suggest that if you are going to rebuild your motor just take it to your local machine shop and have them line hone your mains($120) so that
1.) your bearing tolerances are perfect
2.) your mains are perfectly aligned. We are using aluminum blocks here & aluminum does move around from time to time.

 

i have the ACL's for my engine and the mains were black,black,brown,black black/ hopefully everything will be within tolerance. anyone else had black mains and used Acl's?

I had my machine shop do this. Everything was very close to begin with. But you can never be to safe.

 

stick with oem trust me u will have to break it in of course b/c of tight clearences though which sucks i know

 

ACL's are a tri-metal design, just like original honda bearings. Other aftermarket bearing makers cannot make that claim. They stand-up in our 10,000+ rpm motors.

There you have it.

 

Two of my friends run ACL and never have a problem. My question is if I run them, I can push 10,000+ rpm safely assuming I've modified my valvetrain, correct? If so, I'm getting them too.[QUOTE=TurboB16aEG]

 

As long as you check the clearance is within the spec., I don't see why not.

 

so i have all green and one blac, is it safe to get acl's it my first rebuild and i dont wanto mess anything up

 

I prefer and will only use OEM honda bearings. If you want your motor to be just in "spec" and have your clearances everywhere then get ACL. If you want to have everyone of your mains to have all the exact same clearances then get OEM. The thing with this is that you need to have alot of colors handy do accomplish this.

When I built my motor I used the system that the ITR uses with a split bearing system. For example I used a green upper and a brown lower to get the exact spec I wanted for each journal. This ensures me that I know that all my clearances are the exact same.

Correct me if I'm wrong, but doesn't GE use ACL bearings when assembling blocks?

Yes they do

 

I used ACL withg great success, my main were green and brown color on the OEM, my rod were green and yellow. All the specs were right dead on. The only reason at that time was becasue honda was backordering the green bearing on antionwide basis. If you can go OEM , go for it, otherwise ACL is fine as well.

What most Honda only guys don't realize is that Honda is the only manufacturer to use this color system. 99% of the manufacturers of engines have one size fits all bearings, just like ACL.
JG uses .002" clearance on all of it's builds. Someone else does it at .0017" another at .0018". Who is to say what is the right clearance? Helms? They are figuring on cast pistons and stock rods. Their clearances are based on factory recommended oil weights. We modify evertyhing else. Why is that bearing clearance so important as long as it is within a given range? Your motor is an ignorant piece of metal and won't know the difference between .0017" and .0018". Most everyone switches to an aftermarket rod anyway. That throws the color system out the door. Use Honda bearings if you think their quality is better than everyone elses but to stress over a color change to effect .0001" is not critical.

Well said earl the ACL are just as good

 

OEM is the way to go.

It all preference.. Guys been making alot of pwr with and without OEM. Its personal preference. both of them do work as long as they are in spec.

 

Well said. I would run the acl then speak to someone good in oil to suit your clearances temps etc. Thats what I did ACL and redline oil all the way.

 

Well said Earl.

My clearances came dead on spec with the ACL's anyways.

honda guys aren't the only ones, Isuzu has been known to use the color code system, at least they did on the impulse/storm engines.. but again you are right, i belive one reason honda and a select few other manufactureres gets the bearings to within a very exact spec, is to get the tightest safe possible specs from the factory, so you have a very long lasting even wearing engine, probably one reason why many 80's hondas are still driving around today..
